Final answer:
People may come early in the morning for events like a lavish breakfast, engaging in trade or exchange goods, or cultural practices and routines.
Step-by-step explanation:
The reason why all the people came early in the morning can vary depending on the context. In some instances, people might come early in the morning for specific events, such as a lavish breakfast provided at someone's expense. This can be seen in the quote where people hurl themselves at the breakfast with the appetite of healthy men after a hard night's work without sleep.
In other instances, people come early in the morning to engage in trade or exchange goods. This is evident in the quote where men come to the shore in the morning loaded with various items like cotton, parrots, and javelins, which they exchange for other goods.
Additionally, people might come early in the morning due to cultural practices or daily routines. For example, in the quote, a person remembers going to a garden every morning to weed crops, and their brother chose to wait for breakfast before joining them.
